Hi, this is my 1st post on this board. I'm practicing bass to play out w/my band, been playing guitar- mostly acoustic- for over 20 yrs, electric bass for not long. OK so, I ain't ignorant, I just ain't been educated. I just bought a P-bass, really its a MIM Special with a Jazz neck (maple), Jazz bridge p/u & active electronics. (Don't be knockin' it, because I'm in love) I also have a MIK Hartke w/active p/u's, which actually plays real nice just not nailing the sound I want. I find that when using the P-bass p/u only, its near the sound I'm looking for. It's got the stock Fender strings on it now, roundwound. I have a set of Rotosounds on the Hartke & a new set of DR Hi-Beams in the box. But based on things I've read, like slaying people 'cuz they "showed up with flatwounds", I'm curious about putting flatwounds on the Fender- what do I gain with flatwounds, what's the deal with them vs roundwounds? FYI, we are (trying to be a good) hard/funk rock cover band- the Clash, Kravitz, INXS, Led Zep, jam-band stuff, reggae etc. I know you'll wanna know what amp I'm using but I'm already too long with this question!!! I have a Hartke kickback for now.
